Research On Rural Water Quality Assurance Methods And Landscape Construction Models In Guanzhong

In recent years,with the rapid development of urbanization,waterlogging ponds,which are unique wetland landscapes in the rural areas of Guanzhong,are gradually decreasing,and their functions of flood prevention and drainage are gradually lost,and they are abandoned as garbage dumps and stinking puddles.Since the 18 th National Congress of the Communist Party of China,new rural construction and aquatic ecological civilization have been valued,and a large number of waterlogging ponds have begun to resume construction.However,during the construction of the waterlogging ponds,most of them focused on the application of engineering and technical measures,while ignoring the landscape effects and use functions of the waterlogging ponds themselves.The lack of ecological design considerations in the design generally led to severe water pollution in the waterlogging ponds.The aquatic environment in the villages has been damaged.This article will comprehensively study the waterlogging ponds from the aspects of water quality guarantee and landscape construction,and discuss how to make the rural waterlogging ponds in Guanzhong have a stable water quality purification system while meeting people’s landscape functional needs.This thesis takes Guanzhong rural waterlogging ponds as the research object,summarizes and analyzes the relevant theoretical methods of water purification and landscape design by combing and analyzing relevant literature.Through investigation of representative rural waterlogging ponds in Guanzhong,it summarizes and summarizes the effects of waterlogging.The leading factors of the water quality of the pond and the surrounding landscape environment,as well as the constraints of the construction of the waterlogging pond,propose a set of low-maintenance and low-cost design methods that are suitable for rural areas in Guanzhong to meet both ecological functions and landscape function requirements.Research through traditional water purification technology including using unused land to expand the volume of the waterlogging pond to increase the current waterlogging depth of the waterlogging pond and plant purification technology,combined with modern ecological purification technology including water filtration system design,artificial wetland technology,ecological landscape floating island technology,and aquatic plant purification technology Study on the water quality guarantee construction model of Guanzhong rural waterlogging ponds,such as the oxygen-dropping oxygenation contact oxidation technology and subsurface flow artificial wetland water circulation technology.At the same time,the methods and models for constructing Guanzhong’s rural waterlogging pond landscapes are proposed from the two levels of macro space and micro elements,and specific design methods and guidelines for each type of landscape space and element are proposed.The research results are based on the concrete design practice of the waterlogging pond in Bigong Village,Yangling,Shaanxi Province.The design method and research ideas of this paper are verified.This provides a more scientific and systematic theoretical guidance for the design of the waterlogging pond in the future.Construction provides a new set of design methods and design concepts,as well as a new construction model.
